Rave Party is a physical ability, and Neon Kat's signature ability.

Neon Kat using Rave Party on Cave Kat
Effect[]
Base Power: 5
Accuracy: 70%
Element: None (Physical)
Rave Party deals 5 damage from each of the elements. Since there are 10 (Including physical), it pretty much deals 50 damage. Weaknesses and strengths still effect all of the hits.
Strategy[]
If you use Monochrome World before you send out Neon Kat (Neon Kat doesn't learn it), combined with a high power stat, Rave Party could deal some pretty high damage alltogether.
